Summarise the Tax-Free Allowances That Apply to a Windfall

An unexpected sum lands and the instinct is to worry about tax before checking what is actually taxable. This summarises the personal savings allowance, dividend allowance and ISA allowance in plain terms, as general information rather than personal advice, with a nudge to check current figures before deciding anything.

Summarise, in plain English, the main UK tax-free allowances someone should know about after receiving a windfall of {WINDFALL_AMOUNT}, such as the personal savings allowance on any interest it earns once saved, the dividend allowance if it is invested, and the annual ISA allowance as a place to shelter it from future tax. Keep the summary to what generally applies, note that this is general information rather than personal tax advice, and end with one practical next step: checking the current allowance figures before making a decision, since they change with each tax year.
